As a salt shortage looms over Ohio’s Miami Valley, some agencies are looking to sand and gravel as a road clearing solution.

The city of Trotwood is using sand and gravel to supplement what salt it has, mixing the salt with the aggregate for use in removing ice and snow from roads, WDTN reports.

The report notes that the city recently received 250 tons of salt — 500 tons less than it was expecting. Trotwood intends to mix the salt with enough sand and gravel to provide 500 tons of salt/aggregate mix.

The city’s salt supplier, Cargill, told WDTN that it is mining and shipping the salt as quickly as it can.
